REGISTERING TICKET PUNCH.

Application filed. filctober 14, 1921. J Serial No. 507,695.

T all who m it may concem Be it known that we, FRANK MATHEWS and STANLEYDRUMMOND BLACK, subjects of the King of Great Britain, residing,respectively, at 50 Compton Road, Croydon, Sun rey, England, and 56Tabernacle Street, London, England, have invented new and usefulImprovements in Registering Ticket Punches, of which the following is aspecification.

This invention relates to registering ticket punches used by conductorson street passenger vehicles for checkingthe issue of tickets, of thekind in which a bell is sounded and in which the complete reciprocationsof the ticket punch are controlled through the medium of a double rackand a double armed rocking pawl engaging therewith, the object of theinvention being to improve and simplify the construction, and to renderthe instrument more reliable and less subject to breakdown through wearof working parts than heretofore.

According to our invention the main operating spring which alsofunctions for operating the gong hammer. is locatedswithin a slot in themain slide which is in the form of a link pivotedto the head slide anddirectly or indirectly to the operating lever.

In a suitable arrangement for carrying out the invention the main slideis slotted l0ngitudinally and the main spring is arranged within thisslot, one end of the spring bearing against one end of the slot whilstthe otherrend of the spring bears against one side of a plunger or blockslidable within the slotand the opposite side of which block is fiat andbears against a fiat face on the boss of the gong hammer. This bosspasses through the slot in the main slide and is pivoted to the'base ofthe ticket punch. To

the main slide is pivoted the double-armed rocking pawl, whilst thedouble rack for engagement therewith is pivoted to the base, of thepunch and connected to the said pawl by a spiral spring, the said doublerack being capable of a rocking movement on its pivot and which motionis limited by a pin engaging a slot. The gong hammeris actuo ated by aprojection on the double armed rocking pawl engaging and riding past aprojection on the said hammer.

In the accompanying drawing- 7 Figure 1 is a front elevation of part ofa registering ticket punch illustrating the improvements.

All the foregoing parts are of usual construction. I y

We will now describe the improvements. It is the main-slide whichis inthe form of a link connecting the head-slide cl with the operating levere by means of the'pivot pins As clearly indicated in Figure l, the linkit and lever e are so relatively positioned as to impart a minimumlateral movement to,

the said link during the reciprocations of the punch c. The main slideit is provided longitudinally with a slot j, a pin is secured to thebase-plate a projecting through the lower end of the said slot'andhaving pivoted thereon the hammer Z for striking the gong 92 In theupper part of the slot j is arranged the main actuating'spring m ofspiral form, one end of which bears against the upper end of the saidslot, preferably through the medium of a plate 12 having a downwardlyextending pin 0 to receive the spring. The other or lower end of "thespring bears against a plunger or block 29 the lower face 9 of which isflat and the upper part of which consists of a pin which extends into alongitudinal recess in the pin 0, and telescopes within the pin 0. Theface 9 of the plunger bears against a fiatface r on the boss of thehammer Z andholds it in the position indicated clearly in Figure-l bythe thefiill operations ofthe lever in opposite directions, 1 the tooth25 of the pawl= being held in engagement with the rack' teeth a duringthe downward movement of the main slide'jhiibya relatively weak spring25 attached at one end to the rack u. The pawl "has a nose or projectionwhich presses back the hammer Z by contact with a projec tion Z thereon,during such downward movement, and releases "it to-st'rike th'e gong '9by iding. ov r,
